Question

Determine whether each ordered pair is a solution of y = x+3. (2,5) (4,6) (5,8) (3,7)

Answer 1

Answer:

[see below]

Step-by-step explanation:

$y=x+3$

(2,5):

$5=2+3\\\\\boxed{5=5}$

The ordered pair is a solution.

(4,6):

$6=4+3\\\\\boxed{6\neq7}$

The ordered pair is not a solution.

(5,8):

$8=5+3\\\\\boxed{8=8}$

The ordered pair is a solution.

(3,7):

$7=3+3\\\\\boxed{7\neq 6}$

The ordered pair is not a solution.

Hope this helps.

Answer 2

Answer:

(2,5) and (5,8)

Step-by-step explanation:

you can just plug in the numbers to get your answer and if two numbers aren't the same then its not a solution

example: (2,5)

5 = 2 + 3

5 = 5

5 does equal 5 making it a solution because it makes sense right?

example: (4,6)

6 = 4 + 3

6 = 7

this isn't a solution because six doesn't equal 7
